  • the AC impedance measurement module 310 calculates AC impedance by applying AC voltage or AC current to the battery 400 and measuring the current or the voltage based on a measurement condition received by the AC impedance measurement condition setting module 320 from a user. The measurement is performed over a plurality of frequencies and the result thereof is stored as Nyquist diagram data, for example, on the measurement data storage module 330 as a memory region.

That is, the P values in the equivalent circuit model are set prior to the actual battery degradation determination, and the set P values are used as fixed values to perform fitting of the equivalent circuit model.
  • CPE constant T is the only unknown circuit constant in the CPE, and therefore, it is possible to reduce the number of unknown circuit constants even in the equivalent circuit model including R and CPE parallel circuit blocks to the same number as in the CR parallel circuit blocks. Accordingly, it is possible to reduce the fitting error without increasing the number of unknown circuit constants.
  • the pre-set P values are used to perform fitting of the battery as a target of the degradation determination since it has experimentally been verified that the P values can be regarded as constant values in a same type of battery regardless of a degree of degradation to an extent that the characteristic as a battery is not greatly damaged, an SOC, a temperature, and the like.
